There are calls for a former Big Brother contestant to be banned from Twitter after he mocked Gary Barlow's stillborn baby online.

Kenneth Tong posted a number of offensive statements on his account about the grieving musician's late daughter Poppy.

He then offered to stop in exchange for a tweet from model and actress Rosie Huntington-Whiteley, who later blocked him.

Tong went on to suggest the controversy he had caused should enable him to be given a "verified" account on the social networking site.

The comments prompted an outpouring of anger on Twitter from fans and celebrity friends of Gary Barlow and his wife Dawn.

Among them, fellow X Factor judge Louis Walsh, who wrote: "How DISGUSTING. This man should not be allowed on twitter. RETWEET this if you want him banned!"

Tong, who appeared on series ten of Big Brother in 2009, referenced lyrics from a number of Take That songs in the series of tweets directed at 41-year-old Barlow.
